Fig. 3 is a transverse section on the line 3 3 of Fig. 2.

Fig. 4 is a face view of the other of the muntins Which forms a part of our invention and Which is designed to interlock With the muntin as shown in Fig. 2.

Fig. 5 is a view showing the muntin illustrated in Fig. 4 in a position ready to be interlocked with the muntin illustrated in Figs. 1 to 3 inclusive.

Fig. 6 is a view of similar nature to Fig. 5 showing the muntins in their finished interlocked positions.

Fig. 7 is an inverted plan View of Fig. 6.

Referring to the drawings, 1 and 2 represent the muntins forming a part of our improved sash joint and which are preferably made out of metal. The muntin 1 has an elongated head 3 from which projects a flat rib 4. This rib 4 has a slot 5 which extends from the bottom surface 6 of the head 3 to- Ward the edge surface 7 of the rib 4. This slot 5 is preferably rectangular as clearly shown in Fig. 1.

The rib 4 is split at 8, said split extending from the bottom of said slot to the edge surface 7 and in alinement with the surface 9 0f the slot 5, thus a lug l0 is p I'QVded and sp'eciacation ofretterratnt.

The muntin 1 is then bent into its normal position, such for example as shown in Fig. 1, and thereby the tWo muntins are interlocked, this position being shown in Figs. 6 and 7.

While We have described our invention as taking a particular form, it Will be un-Y soy to make such changes and alterations as fairly come Within the scope of the appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. A sash joint including tWo muntins, oney muntin having a slot extending transversely Within its width and being split, said split extending from said slot to-one edge to form a lug between one end of said slot and said edge, the otherof said muntins having a portion designed to lit Within said Slot and. being gravide@ with a antan into joint including two muntins,

one inuntin having a slotextending trans- Y versely within its width and being split,

`said split extending from said slot to one edge to forni a lug between one end of said Y slot and said edge, the other of said Inuntins having a portion designed to t within said slot and being provided with a notch into which said lugv extends, said latter 1nentioned niuntin having a second notch, said first-mentioned inuntin having its portion which'is oppositely disposed from said lug vadapted to enter said second-mentioned notch, substantially as described.

3. A sash joint including two muntins each having an elongated head, and a rib projecting from said head, one of said muntins having a slot formed in its rib, said slot stopping short of the outer edge surface of said rib, said ri'b being split from said edge surface into said slot toprovide a lug, the other of said inuntins having notches cut respectively through said head and inwardly from the outer edge surface of its rib, said latter mentioned niuntin having the portion between said two notches designed to extend within said slot, said lug being adapted tov enter the notch which extends inwardly from said edge surface, the head of said rst-mentioned niuntin being cut away for a portion of its thickness to pro- Gopies of this patent may lbe obtained for nafiaeac vide a portion adapted to enter the other of said notches on the second-mentioned niuntin, substantially as described.

4:'. A sash joint including two niuntins Yeach having an elongated head, and a rib projecting from said head, one of said Inuntins having a slot formed in its rib, said slot stopping short of the outer edge surface of said rib, said rib being split lfrom said edge surface into said slot to provide a lug, the other of said inuntins having notches cut respectively through said head and inwardly from thel outer edge surface of its rib, said latter mentioned muntin having the'portion between said two notches designed to eX- tend within said slot, lsaid lug being adapted to enter' the notch which extends inwardly from said edge surface, the head of said first-mentioned muntin being cut away for av portion of its thickness to provide a portion adapted to enter the other of said notches on the second-mentioned muntin, said split being formed in alineinent with one side surface of said slot, substantially as described.
